Dear DL-Learner developers and users, in the past year, we performed a lot of changes in the DL-Learner framework and widened its scope to other machine learning problems in the Semantic Web apart from learning OWL class expressions. To give you a preview of those changes, we made an alpha release of DL-Learner today. Our plan is to follow up with further pre-releases until we can roll out a stable version again. Warning: We expect this alpha release to be quite unstable and documentation is not complete yet. Please report issues or feature requests here: http://sourceforge.net/tracker/?group_id=203619 Release download: http://sourceforge.net/projects/dl-learner/files/DL-Learner/ Here is a summary of the changes since the last stable release (from 2010-08-07): * support for new learning SPARQL queries - see http://autosparql.dl- learner.org for a demo (QTL algorithm) * support for learning almost any OWL axiom given a SPARQL endpoint as background knowledge * support for enrichment of large knowledge bases (just run the enrichment script provided in the release to get an overview) * preliminary support for learning fuzzy OWL class expressions contributed by Jousé Iglesias * transition to Maven (http://en.wikipedia.org/wiki/Apache_Maven) - allows easy inclusion of DL-Learner in your Maven projects: http://dl-learner.org/wiki/Maven * new DL-Learner configuration based on Spring (http://www.springsource.org) - IMPORTANT: the conf file syntax has changed, so you will need to adapt existing files * transition to OWL API 3.1, Jena 2.8.8, Pellet 2.2.2, HermiT 1.3.3 * more examples for applying DL-Learner * numerous bug fixes and smaller enhancements in overall close to 1000 Subversion commits from 12 contributors Thanks to Lorenz Bühmann, Chris Shellenbarger and Sebastian Hellmann for their work on DL-Learner.
